Examine the pattern row-wise:
- First row: $16 \times 14 - 14 = 224 - 14 = 210$.
- Second row: $14 \times 12 - 12 = 168 - 12 = 156$.
- Third row (missing number): $12 \times 10 - 10 = 120 - 10 = 110$.
Thus, the missing number completes the pattern where each row’s calculation is the product of the first two numbers minus the last number in the row.
